Mostly likely the update over the air downloaded the wrong archive, which failed to automatically install. In addition to that I found on several forums that the phone had many broken stuff after such update. Therefore I've decided to update it manually.

I've downloaded the zip archive with latest official firmware, put it on my sdcard, rebooted the phone into recover console. It automatically found my zip archive and the phone was updated. Everything works fine now.
